Thanks for the response! I think I agree with your line of thinking. They would be way too similar to the returned if they were actually cognitive shadows. I was initially wondering because it seemed like when Raoden and others are taken by the Shaod their body is almost stuck in a death/dying phase before coming back full of investiture… but I think I agree that they aren’t actually dying and lingering like the typical cognitive shadow. More similar to a misting/mistborn snapping maybe.
Maybe the Elantrians have a ritual process of turning themselves into cognitive shadows when they are ready to move on? I like the idea of how they would have to be accessing or using AonDor when they died to potentially become a cognitive shadow. But, is there any benefit to being a cognitive shadow over an Elantrian, or is that a step down?
Anyway, thank you for listening to my Ted talk of rambling thoughts lol
